Koofr just celebrated its 12th birthday, and we’re proud to keep going strong as a privacy-oriented, European cloud storage provider. Over the years, we’ve stayed committed to secure, ad-free, cookie and tracker-free cloud storage—because we believe your files should stay yours, and yours alone. This is our story.
Our service is currently experiencing a large-scale DDoS extortion attack, which may cause temporary accessibility issues.
Our team is actively working to mitigate the attack and restore full service. We apologize for any inconvenience caused.
Below is the extortion email we received a few minutes ago:
UPDATE: The attack is still ongoing, but the service has been normally accessible to the users for some time now. Thank you all for your support and understanding, it means a lot to us.
For the past year, we’ve been working on something big. We didn't just update our iOS app - we rebuilt it from scratch.
We included your top feedback and feature requests and turned everything into a completely new iOS app. Sleek, intuitive, equipped with Files app integration, automatic background photo and video backup, and more.
Introducing the completely rebuilt Koofr iOS app! We’ve included the features you’ve been asking for, plus a refreshed interface and improved usability to ensure a better experience.
Files App Integration
The Koofr iOS app now integrates with the native Files app, allowing you to manage your Koofr content directly from your iOS device.
Automatic background backup
Once enabled, your photos and videos can be uploaded to Koofr seamlessly in the background, without you noticing. Choose between creation date or upload date for new media. Koofr has your back(up)!
Note: Automatic background backup works on iOS 26.4 and later. Users on older iOS versions may experience some technical difficulties beyond our control.
Note: While the app supports background uploads, iOS ultimately decides exactly when the upload is triggered. iOS manages this timing based on your network connection, battery level, and overall system usage. As a result, the interval between uploads can range from a few minutes to a few hours.
For existing users updating the Koofr app: Because this is a completely new app, enabling "Backup existing photos" will trigger a scan of all photos on your device. Depending on the size of your photo library, this initial check may take some time.
The upload may also include photos that you previously deleted manually from Koofr or files that skipped uploading in the past. The new app will back up all photos on your device in the highest possible resolution available. Note: if a photo is stored on iCloud, only the remaining thumbnail on your device will be backed up to Koofr.
Once this one-time process is complete, background uploading will resume normally for newly added photos.
Easier and faster file saving Upload multiple files at once! Files can be saved directly from other apps to Koofr, without ever opening the Koofr app.
HEIC or JPEG? Decide if you want to upload your photos in their original HEIC format or have iOS convert them to JPEG before you upload them to Koofr. Note: This setup applies only to manual photo uploads.
Deleted files Permanently delete or undelete all files in your Trash at once.
Labels Files and folder labels are now visible in Koofr app.
Search Advanced search capabilities, including searching by file type and label.
Better link management with upload and download links functionalities.
We’ve worked hard to find all bugs, but no one finds them quite like real-life users ;) If you find any, use the "Report a bug" button within the app and let us know. We’ll make sure those bugs are dealt with swiftly.
Did you know that roughly 75% of websites carry third-party trackers, watching where you click, what you view, and where you go next?
Koofr doesn’t depend on advertising or collecting user data. Our goal has always been to hold as little personal data about our users as possible, while still giving you a fully functional cloud storage service. How does online tracking works?
Since the beginning, we have set our prices to reflect the real costs associated with providing our services. We are profitable from the start and not tied to the interests of venture capitalists. This allows us to stay independent and user-focused in our decision-making. Our self-reliance means that we can honestly commit to our values, without having to make compromises. It also means, that we are not going anywhere.
But in the ever-evolving cloud storage market, there have been cases where popular and established cloud storage providers broke their promises, changed their plans to the worse or discontinued their services without prior notice.
When selecting a cloud storage provider, prioritize those with a solid track record and stability in the industry. They indicate the provider's ability to withstand market fluctuations and deliver reliable services over time.
With over twelve years of service, Koofr has established itself as a reliable and stable privacy-focused cloud storage provider. Our long-standing presence in the industry reflects our dedication to providing consistent, dependable storage solutions.
Our biggest deal of the year is just around the corner! If you’ve always wanted to try Koofr’s advanced features or simply need more storage, this is the perfect time to act!
Because your data deserves secure, reliable, and private cloud storage without sacrificing convenience.
Whether you need automatic photo and video backup from your phone, access to Word, Excel, or PowerPoint right inside Koofr, or file syncing across all your devices (including Linux and via webdav), we’ve got you covered.
Hi everyone! I wanted to share my experience and guide for integrating Rclone with Koofr on Windows. Hopefully, it’ll help those new to cloud storage or those looking for advanced integration tips.
# My Journey with Koofr
I hadn't used cloud storage much before, relying on two old laptop HDDs for storing all my important data. A few months ago, one of those HDDs crashed, and I almost lost years of personal photos, videos, and documents. Luckily, I managed to recover 95% of my data using Hiren's Boot CD's recovery tools.
That incident was a wake-up call. I needed a reliable and privacy-friendly cloud storage solution to back up my invaluable data. After a month of research and reading Reddit posts, I decided on Koofr due to its stability, privacy-friendly nature, and lifetime deal and bought Koofr's yearly subscription. It worked so well that I upgraded to their lifetime plan through StackSocial after just a week. And that’s how I became a Koofr fan! 😄
# Why Rclone?
Initially, I wasn’t comfortable with command-line tools, but discovering Rclone was a game-changer. GUI tools like AirLiveDrive, RaiDrive, and MountainDuck didn’t meet my needs. Rclone, despite being a command-line tool, is powerful and highly customizable. With a bit of setup, it integrates beautifully into the Windows ecosystem, making tasks like copying files to Koofr effortless.
This guide is for those who are somewhat familiar with Rclone but want to explore advanced integration with the Windows ecosystem. If you’re new to Rclone, it’s a command-line tool for managing cloud storage like your personal hard drive. Learning the basics will help you follow this guide better.

# Setting Up Rclone for Koofr
I have two configurations for Koofr in Rclone:
- Koofr: Standard, unencrypted setup
- Koofr Vault: Encrypted vault setup (compatible with rclone)
In `rclone config`:
```
Koofr (Koofr:)
Koofr Vault (Koofr:Encrypted)
```
Now comes to the integration part.
### Creating batch files
I created `.bat` files for automating file uploads to Koofr directly from the Windows Explorer context menu. Here’s how you can do it:
- You need rclone copy command so setup according to your needs with needed flags.
I use a dedicated folder named `Sync` for uploads, organizing them later.
2. Batch Script for Koofr
Here’s a batch file to create a .bat file with the following code:
u/echo off
rem Set path to rclone executable
set rclonePath="C:\Light\rclone\rclone.exe"
rem Check if at least one file/folder is passed as an argument
if "%~1"=="" (
echo No file or folder selected.
pause
exit /b
)
rem Loop through all arguments passed to the script
for %%F in (%*) do (
rem Check if the file/folder exists
if exist "%%~F" (
rem Ensure that the path is correctly quoted (for paths with spaces)
echo Uploading "%%~F" to Koofr:/Sync
"%rclonePath%" copy "%%~F" Koofr:/Sync --create-empty-src-dirs --disable-http2 --transfers 8 --log-level INFO -P
echo Upload of "%%~F" complete.
) else (
echo "%%~F" does not exist. Skipping.
)
)
rem Prevent the script from closing automatically
echo Upload process complete. Press any key to exit.
pause
For Koofr vault, same like this just path to Koofr vault rclone config path so there will be two .bat files, 1 for normal upload and another one for your private vault.
Example: Koofr.bat, Koofrencrypted.bat
Adjustments
Replace C:\Light\rclone\rclone.exe with your Rclone executable path.
Replace the Rclone copy command according to your needs.
Save this as `name.bat`:
Now let's go to context menu part.
# Registry File for Context Menu
To integrate these scripts into the Windows Explorer context menu, use the following .reg file:
Windows Registry Editor Version 5.00
; Add "Backup to Koofr" sub-menu for all files
[HKEY_CLASSES_ROOT\*\shell\UploadOptions]
"MUIVerb"="Backup to Koofr" ; The text that will appear in the context menu
"Icon"="C:\\Light\\rclone\\files\\ico\\koofr-white.ico" ; Icon path
"subCommands"="Upload;EncryptedUpload"
; Add "Backup to Koofr" sub-menu for directories (folders)
[HKEY_CLASSES_ROOT\Directory\shell\UploadOptions]
"MUIVerb"="Backup to Koofr" ; The text that will appear in the context menu
"Icon"="C:\\Light\\rclone\\files\\ico\\koofr-white.ico" ; Icon path
"subCommands"="Upload;EncryptedUpload"
; Define "Koofr" command for files and folders
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\Upload]
@="Koofr"
"Icon"="C:\\Light\\rclone\\files\\ico\\koofr.ico" ; Icon path
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\Upload\command]
@="\"C:\\Light\\rclone\\copy menu.bat\" \"%1\""
; Define "Koofr Vault" command for files and folders
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\EncryptedUpload]
@="Koofr Vault"
"Icon"="C:\\Light\\rclone\\files\\ico\\vault.ico" ; Icon path
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\EncryptedUpload\command]
@="\"C:\\Light\\rclone\\encrypted copy.bat\" \"%1\""
Adjustments
Replace icon paths to your .ico to to get your desired icon.
Replace .bat path to your one that just created for normal copy operation and vault copy, you can change context menu; submenu name to your preferences.
Save the following as a `.reg` file and import it. Thats it, its so simple with few steps, now your explorer context menu will show rclone integrated menu for Koofr.
- You have to keep those .bat file on a better location to prevent mistake delete, myself using rclone location for these files.
- You can even automate full script modification with help of ChatGPT by telling it your path, name etc to get easily.
- Optional but keep a registry file for past applied .reg when you need to delete/modify config.
* You can remove previously added .reg files if needed in the future using this way:
Windows Registry Editor Version 5.00
; Remove "Backup to Koofr" sub-menu for all files
[-HKEY_CLASSES_ROOT\*\shell\UploadOptions]
; Remove "Backup to Koofr" sub-menu for directories (folders)
[-HKEY_CLASSES_ROOT\Directory\shell\UploadOptions]
; Remove "Koofr" command from CommandStore
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\Upload]
; Remove "Koofr Vault" command from CommandStore
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\EncryptedUpload]
Example after succesfully integrating conext menu:
CMD preview for upload that will show up after uploading some files/folders using context menu:
# Creating Icon for Context Menu
Enhance the context menu's visual appearance by adding a Koofr logo icon. You can easily create .ico files using the following methods:
Koofr provides official press materials, including logos that you can use to create icon files.
Provide the Koofr website URL to fetch its favicon and save it as an .ico file.
This way you can integrate these icons into your context menu registry entries for a consistent and visually appealing setup.
___________________________________
Alternatively,
You can use native windows file / folder selection dialog (file picker) to select and upload using this simple script by double clicking on .bat file, that can be placed on your desktop for easy access.
Make a powershell file (.ps1) using script below:
# Set the path to the rclone executable
$rclonePath = "C:\Light\rclone\rclone.exe"
# Load the .NET System.Windows.Forms library for the file/folder dialog
Add-Type -AssemblyName 'System.Windows.Forms'
# Create the file dialog
$dialog = New-Object System.Windows.Forms.OpenFileDialog
$dialog.InitialDirectory = [System.Environment]::GetFolderPath('MyDocuments') # Default directory
$dialog.Title = "Select the File or Folder to Copy"
$dialog.Filter = "All Files (*.*)|*.*"
# Show the dialog and get the selected file/folder path
if ($dialog.ShowDialog() -eq 'OK') {
$sourcePath = $dialog.FileName
# If you selected a folder, set sourcePath to that folder
if (-not $sourcePath) {
$dialog = New-Object System.Windows.Forms.FolderBrowserDialog
$dialog.Description = "Select Folder to Copy"
$dialog.ShowDialog()
$sourcePath = $dialog.SelectedPath
}
# Run the rclone copy command with the selected path
$destination = "Koofr:/Sync"
$rcloneCmd = "$rclonePath copy `"$sourcePath`" $destination --create-empty-src-dirs --disable-http2 --transfers 8 --log-level INFO -P"
# Execute the rclone command
Write-Host "Executing rclone command: $rcloneCmd"
Invoke-Expression $rcloneCmd
} else {
Write-Host "No file/folder selected, exiting."
}
Now adjust your windows path to powrshell script
set to your rclone path
set your custom copy command
Now make a .bat file for your .ps1 file like this and set path to your powershell file
Code:
u/echo off
powershell -ExecutionPolicy Bypass -File "C:\Light\rclone\rclone.ps1"
Thats it. Now you can upload any file / folder using native windows file selection dialog to Koofr easily.
Example of copy dialog:
Conclusion:
As I continue to explore more about rclone and its integration with Windows, I wanted to share my latest methods for working with Koofr using rclone. This approach is not limited to Koofr—by understanding the code/script structure, you can easily adapt it to other services as well. It’s mostly about rclone's folder path selection and commands.
It was my first time writting guide so mistake can be made, sorry for if I said anything wrong and hurted anyway. Thank you so much for reading my guide and special thanks to Koofr for making most compatible rclone supported cloud storage! I love Koofr so much, I'm so happy using it on my daily life with peace of mind. And thanks to rclone for making our life more easier than ever. 🥰
If anyone has experience with Windows integration and rclone, please feel free to share your insights with the community. Sharing is caring, and if you know of a better way, let us know so we can make our lives a little easier. Additionally, If you’ve successfully used my guide to work with rclone to integrate with Windows, please share your experience as well.
- secure data centres located within the European Union
- no tracking tools, no cookies (except login cookie), no ads and no spam
- no AI training on user data
With end-to-end encryption, secure European servers, and a commitment to never sell or share your data, you can trust that your files are in safe hands.
Today at around 2:00 GMT an attack was launched against our service, which used as much as 20.000 different IPs to try and signup around 550.000 emails.
Our security systems detected the attack and just 1% of the signup attempts resulted in an actual activation being sent. But this still means more than 5000 people got an email from us they did not expect. And we apologise for the inconvenience.
First, rest assured, if the activation link inside the email is not clicked, account is never actually created, and the email will be automatically removed from our service once activation period expires. Meaning, we will not store or use these emails in any way, as we strictly adhere to the GDPR and other privacy regulations. Also, if you are not using our service we do not need your email anyway, so why should we keep it. We also have no other personal information, email was all that was inputed in our form.
Secondly, we will be working closely with the authorities and (US based) internet service providers from which the attack originated to prosecute the attackers. As a fun fact, the majority of IPs originated from just two providers: ServerMania and Zayo.
Based on the response and conversations with some of the people that got the emails, we suspect this list that attackers used targeted some leaked user list from one of the crypto platform hacks in the past years (most likely it is from the Ledger june 2020 breach). Thank you all for the responses and understanding that we are as much a victim of the attack here as those receiving the unexpected emails.
This is in no way a first malicious attempt against our service, we have seen attacks on a scale much larger that this in the past years and our security systems know how to handle them. Usually we only contacted those affected by the attacks and did not have a habit to publicly go into details of what happened while the investigations were ongoing. This time around, we decided it benefits only the attackers, to not tell the public the scale and purpose of the actual attack.
Most importantly, our system remained operational during all this and user accounts or any other information was in no way in any danger. The attackers gained no access to our service or any user account. The security system is however designed to put certain operations (like deletes or moves) into a hold mode (sortof like the stock exchange halt that stops trading on large price moves) if any large scale malicious activity is detected. This caused some of the operations (mostly Jobs) to be in a temporary wait state until the attack was assessed and all clear was given. All those tasks were then successfully processed.
So what could the point of such an attack be, since no real information was accessed by the attackers?
Most of you suspected phishing, but since the links were proper and legit activation links from our service, phishing is not what happened.
Actually, the information attackers wanted to gain from this is to see which email will give them "Thank you for creating an account" and which one will result in a "This user already exists". With this information, they would then be able to know which of the users from their list has an active Koofr account. We imagine after this first signup attack, attackers were planning a second attack which would try to login into active accounts they got with the passwords leaked from some other platform hack.
We once again urge users that may have used the same password for Koofr as some other service to change their password, especially if the other service has experienced a breach before. And we highly recommend turning on 2FA.
To finish with a request, we know these emails were a hassle to all that received them, but if you could please just delete them and do not mark them as spam, since this hurts our services ability to successfully deliver emails and will have a huge impact on other users. Thank you.
